Definitions

  • the invention relates to a metering device according to the preamble of claim 1.
  • dosing devices For continuous or pulsed dosing of small quantities of bulk solids, especially fine powders, dosing devices with dosing screws are used. They serve as feeders to process equipment or as a device for filling containers.
  • These devices consist essentially of a storage container, one or more metering screws and optionally a stirring member which supplies the material to be metered the screw conveyor.
  • the screw feeder in which the metering screw is arranged horizontally below the reservoir here is the DE 43 36 685 C2 to give as an example.
  • the screw feeder in which the screw is arranged vertically in a rotationally symmetrical dosing and concentrically surrounded by a stirrer as shown in the US 3,269,527 is described.
  • the JP 60 137713 A describes a metering device with a metering screw on the Dosier irritationer anger and a busy with blades rotating stirrer. This conveys the material in the metering device to the discharge tube and prevents material bridging.
  • the DE 645095 discloses a mixing vessel with elevator.
  • a screw conveyor projects with its lower end into the container, the material, here flour falls by its own weight into the height conveyor and is transported upwards.
  • the mixing container is also equipped with a mixing device, eg an upwardly conveying screw.
  • the object of the invention is to provide a metering device which allows a constant supply of material to the metering screw even with difficult flowing bulk materials and which provides a simple disassembly of stirrer and metering screw for cleaning purposes, in particular with regard to the expansion of the product side shaft seals.
  • a significant advantage of the invention is that the worm shaft is not arranged concentrically with the stirrer in the dosing, but eccentric as close to the wall of the dosing.
  • the stirrer is arranged concentrically to the metering container, wherein the stirring arm is guided as close as possible to the container wall. He performs an oscillating movement. This prevents poorly flowable products from being rotated around the screw by the agitator without realizing supply of material to the screw.
  • the material is inevitably guided by the stirrer to the screw, detected by this and transported down through the metering tube.
  • the design of the device with separate shafts and bearings for stirrer and screw allows easy release of the dosing with stirrer and screw from the storage and drive unit. Thereafter, the lid of the dosing, the stirrer, the screw and the shaft seals can be removed for cleaning purposes.
  • the metering device 1 consists of the metering 2 with stirrer and screw and a drive unit 3.
  • the metering 2 is provided with a hopper 4 for the material supply.
  • an automatic feed for example, with a horizontal auger can be used.
  • the supplied material is guided in the dosing 2 by the stirrer to the screw and metered via the dosing 5 a machine, a system or a container.
  • FIG. 2 the metering container 2 with the arrangement of the metering screw 6 and the stirrer 7 is shown.
  • the dosing tank 2 is designed rotationally symmetrical.
  • the screw 6 is arranged eccentrically parallel to the stirrer axis in the metering container 2 as close as possible to the wall of the container.
  • the screw threads extend from the dosing tank into the dosing tube.
  • the stirrer 7 is arranged axially centrally in the rotationally symmetrical metering container 6. By the shaft seals 10, the waves of agitator 6 and screw 6 are sealed against the lid and the environment.
  • the stirrer 7 has a hook-shaped form, so that it is possible wall and near the bottom in the dosing, which is designed rotationally symmetrical at least in the region of the screw outlet.
  • the stirrer 7 can be designed with one arm or with more than one arm.
  • the stirrer 7 performs an oscillating movement. He moves with one arm until just before the screw 6 and transports material before him to transport it into the screw. Then he turns in the opposite direction to also move to just before the snail and transport the material into the snail.
